Abstract

Disclosed is a bead reinforcing structure for a heavy duty tire having a bead in which a carcass is turned up to surround a bead core. The bead reinforcing structure includes a carcass, and an inside steel chafer having a first predetermined inclination angle and an outside steel chafer having a second predetermined inclination angle. The inside and outside steel chafers are disposed inside and outside the carcass, respectively, thereby reinforcing the bead from the inside and outside of the carcass.

Claims

exact text as granted — not AI-modified
1 . A bead reinforcing structure for a heavy duty tire having a bead in which a carcass is turned up to surround a bead core, the bead reinforcing structure comprising:
 a carcass; and   an inside steel chafer having a predetermined inclination angle and an outside steel chafer having a predetermined inclination angle, the inside and outside steel chafers being disposed inside and outside the carcass, respectively, thereby reinforcing the bead from the inside and outside of the carcass.   
     
     
         2 . The bead reinforcing structure for a heavy duty tire according to  claim 1 , wherein the inside steel chafer and the outside steel chafer intersect each other, forming opposite angles in a range of 0° to 90° therebetween. 
     
     
         3 . The bead reinforcing structure for a heavy duty tire according to  claim 1 , wherein the inside steel chafer and the outside steel chafer have corresponding angles in the same direction, and the corresponding angles are in a range of 0° to 90°. 
     
     
         4 . The bead reinforcing structure for a heavy duty tire according to  claim 1 , wherein a height of an end of the inside steel chafer which is near an end of the carcass is higher or lower than that of the end of the carcass. 
     
     
         5 . The bead reinforcing structure for a heavy duty tire according to  claim 1 , wherein a height of an end of the outside steel chafer which is near the end of the carcass is higher or lower than that of the end of the carcass.
